32-7X-5X=30
32-7X-5X=30
32-7X-5X=30
32 - 7x - 5x = 30
7x + 5x = 32 - 30
12x = 2
x = 1/6
32-7x-5x=30
32-12x=30
-12x=-2
x=1/6
(16x-13)/(4x-3)-(20x-24)/(4x-5)=(32x-30)/(8x-7)-(40x-43)/(8x-9)求x
32-7X-5X=30
(16x-13)/(4x-3)+(40x-43)/(8x-9)=(32x-30)/(8x-7)+(20x-24)/(4x-5)....
(16x-13)/(4x-3)+(40x-43)/(8x-9)=(32x-30)/(8x-7)+(20x-24)/(4x-5)
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
2x(7-3x)+5x(2x+1)=x(4x-3)+32
解方程:x/4=30% 36/x=3/4 10/x=2.5/0.8 x/4=1.2/5 X/1.2=1.5/0.6 x/0.4=1.5/6 x/7=0.6/3.5 x/10=0.1/25-3x=8x+1 2(x-2)+2=x+1 3-x=2-5(x-1) 3x=5(32-x) 7(4-x)=9(x-4) 7x-8=2x+27 5x-18=3-2x (7x-4)+3(x-2)=2x+6 2(3x-4)+(4-x)=4x我是六年级的学生,我希望

11(6-x)/3(x-4)=10(5-x)/3(x-4)-5(6-x)/(x-2)(16x-13)/(4x-3)-(20x-24)/(4x-5)=(32x-30)/(8x-7)-(40x-43)/(8x-9)求x(包括增根)
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
